lhisinvention'relates to lubric'atorsand more particularly tocentralized lubri'cators for the lubricationof a pluralityofp'artslocated at some distanoe from the lubricator.

One of the objects -iofftheinvention is to provide a. lubricator; forthe c an automobile whereby the parts are lubricated from a commonsupply. 1

Another objectof the invention is to provide a centralized lubricatorfor the chassis parts of anautomobile in which the replenishment oflubricant will be coincidentalv B with the engine lubrication.

Another object 7 of. the invention is to :pro- 5 vide alubricatorwhereinthe replenishment of the lubricant will be approximately regular.

Another object of'theinventionto provide a centralized lubricator forthe;chassis parts of an automobile in whichthe'fiow of lubricant isincreasedrby gaseouspressure above the lubricant;

Regularity of vehicle lubrication is-also 'secured, as the operator isaccustomed to reignlarlyreplenishthe engine oil supply, and a merecontinuation of his routine in regard a removable cover 2 secured to'thebody pore I tion 3 by clamps 4 and having hand operated Other objects,and objects relating'tode tails of constructionand economies ofmanueccentrics ,5.

Tightly fitted within central opening 12. is a fillertube 16 having ai central passage 17 .and communicating openings; 18 ;inalign-' means of clamps 4, and the engine (not shown) oil supply isreplenished in the usual manner through passage 17. The oil in passingto the engine, flows in the direction shown by the arrows in Fig. .11from. passage :17 through openings "18 into passageway 11 and intoannular space 10. From annular space 10 the flow is upwardly, over thetop of reservoir member 6, in which are located cavities 13, and intothe segmentalpassages 20 which are in direct communication with opening9 in-extension 8. The various openings andpassageways withinthereservoir memable for vehicle lubrication.

ber cause the oil to first fill cavities 13 before entering the engineand thus automatically render a small portion of the engine oil avail-From cavities .13 the oil is led,by means of passages 14 and pipes 15,to the outside of the lubricator and to the parts to be lubricated. Thevehicle parts (not shown) requiring lubrication are ordinarily below thelevel of the lubricator and oil will flow to them by gravity, but inorder to accentuate the flow of oil and to provide lubrication for suchparts as may be above the level'of the lubricator, I provide a fitting22 having a spring loaded check valve 23 which may be connected by tube2 l to theaexhaust pipe (not shown) 'of the engine. Another fitting 25protected by cap 28 and having a check valve 23 is conveniently locatedin cover 2 and provides a means whereby high pressure air may beintroduced to the lubricator and thoroughly clean the small'oiltubes 15.If it be desired, fitting 25 may be omittedand the air pressureintroduced through fitting 22, after disconnecting it from exhaust tube24. "The omission of fitting25 will also remove the necessity for checkvalve -23 within fitting 22, as none is necessary with a single fitting.The preferable procedure in using the air pressure is to apply it, bymeans of the usual air hose ordinarily kept at oilsupply stations,immediately before removing cover 2, as after the cover is removed avisual inspection of cavities 13 may easily be made. If the inspectionrevealsthat all cavities are free from oilit maybe reasonably presumedthat the lubricator is functioning properly and that a replenishingoffthe oil supply is all that is necessary.

Cover 2 is preferably provided with agasket 26'to insurea tightconnection withthe body. A. spriiig loaded member 27 closes segmentalpassages 20 when the cover is in its normal closed position and ismovably secured to the under side thereof by screw 7. Gasket 29 ispreferably secured to the under face of member 27 by being tightlypressed into annular groove 30 and should be formed from an oilresisting material such as fibre. Member 27 because ofthe securing screw7, on which it is slidable, is removed as a unit with the cover 2 sothat passage 17 is unobstructed for the introduction of a supply of oiland in'the normal position of cover 2 presses against reservoir member 6and filler tube 16 which are substantially of the same height at theirpoints of contact with gasket 29. If cover 2 be of sufficientresiliency, member 27 may be formed integral with cover 2, as it willthen be possible to secure sealing contacts'of the gaskets 26 and 29,without permitting any relative movement between member 27 and cover 2.

It may be readily-seen that the lubricator described will cause a freshsupply of oil to be delivered to the vehicle lubricant cavities whenevera fresh supply of oil is added .to the engine, andthat attention needonly be directed to the lubrication supply of the engine, which israrely neglected because of the almost universal knowledge of itsimportance. After'the oil is delivered to the cavities, all outlets fromthe reservoir except the tubes leading from the bottom cf the cavities,are automatically closed by the installation of'the'cover2, and pressurefrom the engine exhaust delivered through fitting 22 will assist thenormal gravity'flow of oil to the vehicle parts.

While I have illustrated and described somewhat in detail, certainembodiments of my invention, it is to be understood that this showingand description are illustrative only, and that I do notregard theinvention as limited to the details of construction illustrated anddescribed,'except insofar as I have included such limitations within theterms of the following claims, in which it is my intention to claim allnovelty inherent in the invention, broadly a'swell as specifically.

I claim asmy invention '1.
